The invention relates to the field of furniture, and in particular to a cushion or mattress suspension element 101, 201, . . . , 901 comprising a compressible core 102, 202, . . . , 902 of flexible material and presenting at least one compression axis Z, and also comprising two bearing parts 103, 203, . . . , 903 of material that is substantially more rigid than the material of the compressible core 102, 202, . . . , 902 , with at least a first bearing part being connected to one end of the compressible core 102, 202, . . . , 902 and at least one second bearing part being connected to an end of the compressible core 102, 202, . . . , 902 that is opposite along the compression axis Z, and with each bearing part presenting an outer bearing area 103 a, 203 a, . . . , 903 a that is substantially perpendicular to said compression axis Z and, in at least one direction perpendicular to the compression axis Z, that is substantially larger than the compressible core 102, 202, . . . , 902 in its relaxed position.
1. A cushion or mattress element comprising:
at least one compressible core of flexible material and presenting at least one compression axis;
at least two bearing parts of material that is substantially more rigid than the material of the compressible core, with at least a first bearing part being connected to one end of the compressible core and at least one second bearing part being connected to an end of the compressible core that is opposite along the compression axis, and with each bearing part presenting an outer bearing area that is substantially perpendicular to said compression axis, and in at least one direction perpendicular to the compression axis, that is substantially larger than the compressible core in its relaxed position; and
at least one spring secured to at least one of the bearing parts and formed integrally with at least one of the bearing parts to which it is secured, wherein said spring includes at least one flexible spring blade.
2. The cushion or mattress element according to claim 1 , wherein the flexible material of the compressible core is a foam.
3. The cushion or mattress element according to claim 2 , wherein said foam is a high resilience foam.
4. The cushion or mattress element according to claim 1 , wherein at least one of the bearing parts presents at least one through orifice for ventilation.
5. The cushion or mattress element according to claim 1 , wherein the compressible core has a cross-section relative to the compression axis that is cruciform.
6. The cushion or mattress element according to claim 1 , wherein at least one of said bearing parts is fastened to the compressible core by clamping against the compressible core perpendicularly to the compression axis.
7. The cushion or mattress element according to claim 1 , wherein said spring is interposed between the bearing part to which it is secured and the compressible core.
8. The cushion or mattress element according to claim 1 , wherein said spring is secured to at least one of the bearing parts at each end of the compressible core.
9. The cushion or mattress element according to claim 8 , wherein said spring is arranged so as to clamp radially against an intermediate segment of the compressible core at least when the cushion or mattress suspension element is under compression.
10. The cushion or mattress element according to claim 1 , having only one of said bearing parts at each end of the compressible core.
11. The cushion or mattress element according to claim 1 , having a plurality of said bearing parts at each end of the compressible core.
12. The cushion or mattress element according to claim 11 , wherein the bearing parts at each end of the compressible core are laterally connected together by flexible connections.
13. A module comprising a plurality of cushion or mattress elements according to claim 1 , wherein at least one of said bearing parts of one of said connection elements is laterally connected by flexible connections to at least one bearing part another one of said elements.
14. A cushion or mattress presenting a top face and a bottom face that is substantially opposite said top face, the cushion or mattress including, between said bottom and top faces at least a plurality of cushion or mattress suspension elements according to claim 1 with their compression axes being substantially perpendicular to said bottom and top faces of the cushion or mattress.
